9.12 Ct. Ruby from Mozambique

As a specialist at The Natural Ruby Company I am pleased to present this exceptional transparent ruby, weighing 9.12 carat, with dimensions 15.09 x 11.06 x 5.89 mm, cut in a classic cushion outline with a mixed brilliant faceting scheme. The mixed brilliant cut combines a brilliant facet pattern on the crown with carefully controlled step and modified pavilion facets to optimize both color saturation and light return, producing a balance of vivid face up color and lively scintillation. The overall depth relative to the average girdle diameter is approximately 45 percent, a proportion that supports strong color performance without sacrificing dispersive sparkle. Facet junctions are executed to precise angles, and the excellent polish enhances light transmission through the stone, producing crisp facet reflections and a pronounced windowing control that preserves the intense red color from table to pavilion. This gem demonstrates the practical advantages of a mixed brilliant cushion for large format rubies, marrying the warmth and depth of a step influenced pavilion with the fire and brilliance introduced by a brilliant crown.

On close inspection the ruby carries a clarity grade of slightly included, evaluated at eye level, consistent with natural corundum of this size and origin, with inclusions that attest to its natural formation while maintaining transparent bodycolor and strong visual appeal. The cutting strategy intentionally retains some internal character to maximize color saturation and maintain structural integrity, rather than overzealously removing material that would thin the color. The stone has been heat treated, a stable and permanent enhancement applied to improve hue uniformity and eliminate strain features, with no clarity enhancing fills or glass treatments involved, ensuring long term stability for wear. The intense color intensity reported reflects a richly saturated red, characteristic of high quality Mozambican rubies, with excellent polish and well executed symmetry that allow the stone to present a lively, evenly distributed red face up. As corundum, this ruby benefits from a hardness near nine on the Mohs scale and excellent resistance to abrasion, making it suitable for fine, wearable jewelry when set in secure mounting designs that respect the stone proportions.

Sourced from Mozambique, this ruby is presented within The Natural Ruby Company ethical sourcing framework, which emphasizes traceable supply chains, transparent documentation, and direct engagement with responsible local producers and cooperatives. We prioritize conflict free procurement, fair compensation for miners, and support for local community initiatives that improve working conditions and long term sustainability on the ground.

Upon acquisition we provide detailed origin documentation and can facilitate independent gemological analysis and reporting if desired, supporting both immediate jewelry design plans and longer term provenance records. This specimen integrates seamlessly into a mindful collection as an investment quality, heirloom capable stone, suitable for bespoke settings that celebrate the stone geometry and color dynamics, while also aligning with an ethical purchasing ethos that The Natural Ruby Company maintains as part of its commitment to thoughtful, traceable gemstone stewardship.
